I bought an 1-2" inside micrometer from one of Our favorite tool resellers. Mic is undoubtedly made from an way off shore company. They supply a ring gauge with the micrometer. Accuracy is said to be .00024". I use the size 1.1811" and the mic reads .0015" too low. I calibrated the mic with the ring setting gauge. The mic agrees with the ring and My Mitityoyo 1" gauge block. I sent the mic back and the company agrees with My findings. The description says the mics are checked at 10 datum points, evidentially not the one I use. They say I am expecting too much from this style mic. What does everyone here think about this?
